LOCK.

Application filed February 12, 1914, Serial No. 818,397.

following is a full, clear, and exact description.

This invention relates to looks, and more particularly to union or escutcheon locks where the key mechanism at the outside of the door is housed in the knob for retracting the latch bolt from the outside of the door.

The primary object of the invention is to improve the general construction and operation of a lock of this type. Another object of the invention is to provide improved means for deadlocking a latch bolt automatically on the closing of the door.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

22 adapted to be operated by a key 23. The inner escutcheon 24 carries a knob 25. The knob 21, pin tumbler lock 22, and knob 25 are each operatively connected with a latch bolt 26, projecting through a face plate 27 carried by the outer escutcheon 20 and extending across the inner escutcheon 24 in the manner shown in Fig. 3.

The outer escutcheon is provided near the upper edge thereof with an inwardly extending wall 28, and near its lower edge it is provided with a similar wall 29, both of which walls are joined with the upper and lower portions respectively of the face plate 27, preferably in an integral manner. An inwardly extending vertical wall adjacent the rear edge of the outer escutcheon (relatively to the front or face of the lock) joins the walls 28 and 29 and forms in connection with said walls, the face plate, and the outer escutcheon, a boxlike case for the latch mechanism, which case is completed by a cover plate or back plate 31, as shown in Fig. 4. This back plate is provided at the edges with lugs 82, 33 and 34 fitting suitable notches in the inner edges of walls 28, 29 and 30, and it is also provided at the upper and lower edges with inwardly projecting lugs 35 adapted for threaded engagement with screws 36 passing through the upper and lower walls of the case, as shown in Figs. 3 and 4. The walls 28, 29 and 30 of the case are provided with threaded sockets 37 adapted to receive the inner threaded ends of screws 38 passing through the inner escutcheon 24, whereby the inner escutcheon may be securedto the outer escutcheon and adjusted relatively thereto in order to adapt the lock to doors of different thickness.

The latch bolt 26 is of the car latch type, being pivoted to the face plate 27 by means of a pin 39. At the rear face of the latch bolt, the same is provided with a groove 42, which is pivoted to the latch bolt by a Fig. 14 is a similar section on line 1414 pin 43 extending through the part'41, as shown in Figs. 9 and 10. The rear extremity of the stem or spindle 42 isguided in a post or standard 44 projecting inward from the outer escutcheon 20, as shown in Fig. 10, said standard or post being provided with a notch 45 in which the stem or spindle 42 is retained by the back. plate 31.

V in Figs. 9 and 10. A washer 56 surround- Above and below the groove in thelatch bolt are grooves 46, in which a yoke member 47 is pivoted by the same pin 43 which pivots the stem or spindle42 to the latch bolt. The yoke member 47 is pivoted to the pin 43 by webs 48 entering the respective grooves 46. Extending rearwardly from the webs 48 are arms or branches 49 which give the yoke member 47 the shape of a fork. The rear'eXtremity of each arm'49 is provided with an inturned wing 50. 'Another yoke member 51, having arms or branches 52 lying against and parallel to the arms 49 of the yoke member 47 is slidably connected with the last named yoke member by a pin and slot connection 53, as shown in Fig. 12. Pivotal movement of the part 51 relative to the part 47 is prevented by providing the former'part with an upturned forward end portion or lug 54, which fits between and in engagement with the webs 48, as shown particularly in Figs. 10 and 12. The lug 54 on part 51 is constructed in the shape of a fork, being provided with a notch 55 engaging the stem 42, as shown f ing the stem 42, and abutting the-lug 54 forms an abutment for the latch bolt spring 57 which is coiled about the stem 42 and re acts at its rear extremity against awasher 58 positioned against the front face of the post or standard 44 (relative to the front or face of the look). In this manner the spring 57 normally holds the latch bolt in its protracted position. 7

r The outside knob 21 is provided with a spindle 59 rotatably secured in the outer escutcheon by suitable means, as shown in Fig. 10, and provided at its inner end with ahub 60. The key mechanism22 comprises a key rod 6l-eXtending through the'spindle 59, and carrying at its inner end a dog 62 adapted to abut either of two pins 63 on a hub or rollback 64, whereby said hub or roll- 7 back may be operated by the key mechanism. The hubs and 64 are nested together in the manner shown in Fig. 10. A third hub 65 is arranged in line with the hubs 60 and 64, and is provided with a sleeve 66 having a polygonal opening 67 fitting telescopicallya spindle 68 rigidwith the inner knob 25. By this construction,

the inner knob can operate the hub'65 irrespective of the adjustment of the escutcheon 24 relative to the latch mechanism, within certain limits,"as the lock is adjusted to 7 doors of different thickness. The sleeve 66 of the hub 65 passes through an opening 66 in the back plate 31, which back plate in overlying a shoulder 65 on the hub .65 at a' point within the casing holds said hub in i 1 position relatively to the other hubs.

turned wings 52 adjacent the 'wingsof the several hubs and interposedbetween said hubs and the wings of the yoke member 47, as shown in Fig. 10. In the normal position of the parts, there is a slight amount of play between the wings 52 and the corresponding wings 50 of the respective yoke members. Hence, when any one of the hubs 60, 64, 65 is turned by its operating member, the yoke member 51 will be moved rearwardly independently of the yoke member 57 until the wings 52 abut the correspond ing wings50, whereupon both yoke members will move rearwardly together, the latch bolt 25 being thereby retracted by virtue of its connection with the yoke member 47. In retracting the latch bolt, the spring .57 is compressed, the stem 42 being guided rectilinearly in the standard 44, so that the latch bolt head is firmly guided and supported in its inward movement. When the hub in question isreleased, the latch b01518 protractedagain man obvlous manner.

The outside hub 60 may be dogged and'released by appropriate night latch mechanism which, in the form shown, comprises a dogging slide 69 having a plunger head or button 7 0, accessible at the face of the look, a releasingslide 71 having a plunger dog said hub against movement, likewise the knob 21 connected therewith. This knob may be released by pushing in the releasing slide 71.

tremity of the latch bolt stem 42, and preferably comprising a lever 77 pivoted ina kerf or notch 7 8 in the standard or post 44. The

deadlocking lever 77 is pivoted intermediate of its ends on a pivot 79, and one end 80 the locking surface81 on the rear end of of said lever is adapted to coeperate with i pushes the end 80 into thepath of the latch bolt stem, as shown in Fig. 14. The dead locking leverjis controlled. in its operation I by the shank 84 of a controller bolt 85. The

controller bolt is preferably pivoted on the same pin 39 which forms the pivot forthe latch bolt, and the shank 84 is pivoted to the bolt 85 by a pin'86, as shown in Fig.9.. The

shank 84 is guidedin the case near the rear end of said shank in a bifurcated lug 87 ,and a V spring 88coiled about the shank 84 between owing-87 and a suitable abutment or enlargement ,89Lon the shank normally holds the controller bolt in its protracted position. The shank 8% is provided with a notched rear extremity 90, which, when the parts are in the normal position shown in Fig. 5, engages and presses downward the end 82 of the deadlocking lever 77, as shown in Fig. 18,

whereby said lever is held in an inoperative position with respect to the latch bolt. hen, however, the door is closed, the controller bolt is held in its innermost position by contact with the-strike 91, as shown in Fig. 6, in which position the notch in the rear extremity 90 of the shank 8% is in line with the lever 77, so that the spring 83 moves the deadlocking lever into the path of the latch boltstem, as shown in Fig. 14:. Hence in this position of the parts, it is impossible to push back the latch bolt by an instrument inserted between the lock front and the strike. When the parts are in the locked position, shown in Fig. 6, the latch bolt may be retracted by any one of the hubs 60, 64, 65, except in the case where the hub 60 is dogged by the stop work, in which event, the operation. of the latch will be confined to the key mechanism at the outside of the door and to the inside knob operating their respec tive hubs. The hub which is used for retracting the latch bolt first shifts the yoke member 51 before the yoke member 47 and latch bolt 25 begin to move, as previously explained. In doing this, a shoulder 92 on the member 51, contacts with the extremity 82 of the deadlocking lever 77, and moves it out of deadlocking position so that when the yoke member 4'? begins to move the latch bolt is free for retraction.

The controller bolt 85 is provided at its rear surface with a pin 93 extending down into the path of the latch bolt, so that in case both bolts are protracted, the controller bolt will be retracted by the incursion of the latch bolt. 7

In applying the lock to a door, the stile of the door is suitably notched to receive the casing containing the latch mechanism, after which the escutcheons are applied from the proper sides of the doors and connected by the screws 88. The upper and lower walls 28 and 29 of the case are provided with transverse fins 94, so that when the outer escutcheon and the parts carried thereby are set into the notch from the face of the door, the fins 5% may be driven into the upper and lower edges of the notch in such a manner as to prevent the displacement of the lock in a direction toward the edge of the door. Moreover, the inner escutcheon 24: is extended back of the outer escutcheon 20 with reference to the edge of the door, as shown in Figs. 1 and 8, and is provided with an opening 95 for a suitable screw, so that the inner escutcheon may be screwed to the uncut part of the door at the inside of the latter. This also prevents movement of the locktoward the edge of the door, and as the escutcheons are tightly clamped on the portions of the door adjacent the edges of the notch, by means of the screws 88, the lock may be securely held in place.
